HYDROCRBON-BURNER.

SPECIFICATION forming' part of Letters Patent No. 552,236, datedDecember 31, 1895. Application led January 24, 1895. Renewed September6, 1895. Serial No. 561,708. (No model.)

To @ZZ wiz/m it may concern:

Beit known that I, JOSEPH DARBY, a citizen of the United States,residing at Springeld, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Hydrocarbon-Burners, ofwhich the following is a specification.

My invention relates to hydrocarbon-burners; and it consists of thenovel construction 1o and arrangement hereinafter set forth and claimed.

In the drawings, Figure l is a perspective view of -my improved burner 5Fig 2, a vertical sectional view, and Fig. 3.a view showing cerr taindetails of construction.

y The object of my invention is to produce a burner simple inconstruction and efficient in operation, and one that may be easily andquickly assembled and taken apart.

The general construction of the burner is similar to that shown andclaimed in my application filed December 2S, 1894, Serial No. 533,185,the present case differing only in the construction of the retort andthe means for adjusting the parts of the burner.

A designates the retort, below which is secured a plate or disk B7provided at its center with a depending conical mixer or funnel O, thewalls converging upwardly or toward the 3o discharge end. Between thisplate and the retort, and over the mouth of the mixer, there issuspended a deector vor spreader D, the stem a of which passes upthrough a square opening b in the retort. The lower portion of the stemis square, which prevents it from turning, while leaving it free to riseand fall.

E indicates the burner or valvelconnected with the outlet-pipe of theretort and located below the mouth of the mixing-funnel. -A series ofholes or openings cis provided around the mixing-funnel to admit air tothe space between the retort and the plate B to insure proper combustionof the gas or vapor.

The retort A comprises a plate F, the coil G, and a cover or cap-plateI-I. The plate F is provided on its under face near its periphery with aseries of downwardly-depending arms or studs d, which are bored through,as seen upon reference to Fig. 2. Upon the upper face at the center isalso a stud or projection K,

provided with a squared opening which passes entirely therethrough, andthrough which opening passes the stem a of the deflector or spreader.

The coil G is constructed of ordinary iron pipe bent to form and restingupon the upper face of plate F. The inlet end of the coil passes througha suitable opening in the side of the cover or cap-plate H, while theoutlet end extends down through an opening in the plate F to a pointconvenient for the attachment of the burner-valve E. The oil is thuscaused to travel through a tortuous passage and is fully exposed to theheat of the burner, insuring proper vaporization. 65

The cover or cap-plate fits over and down upon the coil, and is formedwith lugs or ears f, having' holes or openings which register with theopenings through the studs CZ. Bolts are passed through openings in theplate B, studs d, and ears f, and securely hold the parts together.

The adjusting device for the spreader comprises a collar or Washer I,adj ustably secured to the upper end of stem a, said collar having 7 5two cam-faces g g, forming shoulders or abutments h h. A similar collarJ encircles the stem a below the collar I, the cam-faces of the twocollars working against each other. The lower collar J Y is providedwith an arm or handle 7c. Formed upon the periphery of each collar,adjacent to one of the shoulders h, is a rib a', the end of whichextends beyond the cam-face and bears against the periphery of the othercollar. When the lower collar is so turned that the deflector is in itshighest position, the ends of the ribs abut against each other andfurther movement of the lower collar is prevented, and the deflector issustained in its highest elevation.

It will be seen from the above description that the coil may be readilyremoved or replaced as desired, either for repairs or for any otherpurpose.

Having thus described my invention, what 95 I claim isl. A retort forhydro-carbon burners, comprising a pipe coil removably secured within asubstantially closed compartment.

2. A retort for hydro-carbon burners, comroo prising the combination ofa pipe coil; a plate below said Coil and upon which it rests; and a capplate or cover fitting1 over said ooil7 and secured to the supporting1plate.

3. In a hydro-carbon burner, the combination of a pipe coil; a platebelow said coil and and an adjustable spreader above the mouth of thefunnel.

5. In a hydro-carbon burner, the ombination of a retort; a spreader ordefieetor provided with a stem passing up through said retort; a ealnfaced collar secured to the upper end of said stem; a second Cain facedeollar encircling the stein and bearing against 25 the first collar; andribs formed'upon the eollars` adapted to abut against each other whenthe spreader is in its elevated position.

In witness whereof l hereunto set my hand in the presence of twowitnesses.
